台阶式场地平整的土方优化

The optimization of earth quantity in stepped ground leveling

在台阶式布置中,台阶宽度及高度是决定场地土方量及整体经济效益的重要因素。对于台阶的宽度及高度的确定往往是根据规范或者经验进行简单的分析确定,而这种分析又仅仅考虑使台阶宽度及高度满足平面布置及运输等定性的要求,没有定量考虑对其整个场地土方工程的影响。以定性和定量结合的方法,以填挖方平衡且土方总量最小为目标,建立数学模型,寻求满足规范及经验要求,同时又使填挖方平衡且土方总量最小的台阶宽度及高度。

In stepped ground leveling,the width and the altitude determine the volume of earth worth and the whole economic efficiency.In existing research,when determining the width and altitude,they took a simply analysis according to the needs of standards and experience.But the analysis only considered the qualitative factors,such as the general layout and transportation etc,but never took the influences of the stair width and altitude to the earth quantity in to account.This article sets up a mathematics model based on the method combines qualitative and quantitative methods,seeking for the most suitable width and altitude which not only meet the needs of standards and experience,but also obtain the minimum and balance earthwork.
